NOAA PMEL: Towed CTD on ferry at nominal 4m depth#

CTD Towed 2004-2008 Ferry in-line - NOAA PMEL
ctd_towed_ferry_noaa_pmel
Continuous 2004 to 2008, 5min sampling frequency

An oceanographic monitoring system aboard the Alaska Marine Highway System ferry Tustumena operated for four years in the Alaska Coastal Current (ACC) with funding from the Exxon Valdez Oil Spill Trustee Council’s Gulf Ecosystem Monitoring Program, the North Pacific Research Board and the National Oceanic and Atmospheric Administration. An electronic public display aboard the ferry educated passengers about the local oceanography and mapped the ferry’s progress. Sampling water at 4 m, the underway system measured: (1) temperature and salinity (used in the present report), and (2) nitrate, (3) chlorophyll fluorescence, (4) colored dissolved organic matter fluorescence, and (5) optical beam transmittance (not used in report).

The ferry regularly traveled outside of the domain of interest and those times are not included. Data was resampled from 30s to 5min sampling frequency.
